IMPROVEMENT IN SMOOTHING-HARROWS.`

Specification forming part of Let-ters Patent-No. 196,969, dated November 13, 1877; application filed April 28, 1877.

' To all whom 'it may concern:

Beit known that I, CHRISTIAN K. CHRIS- PENSEN, of Newark township, in the county of Rock and State of Wisconsin, (Beloit P.

' 0.,) have invented a new and useful Improvement in SmoothingHarrows, which improvement is fully set forth in the following specification and accompanying drawings, :in which- Y Figure l is a perspective view of my wire smoothing-harrow, and Fig. 2 a view showing ,how to bend and insert the Wire teeth.

`The teeth B are inserted in the scantlings A A', two inches apart,`as shown at C. Two rows of teeth should be s o inserted in each scantling` that when they are bent back, as

shown at E E," they should be one inch apart, v

which makes a perfect wire brush with twelve No. 5 wire teeth per foot in each scantljng. It should also have a seat attached, which I have not shown in the perspective view, Fig. 1.

It will be seen from the. foregoing that this harrow can be constructed with simple N o.

5 or 6 hard spring-wire and common scantling.

It is obvious that this harrow can be constructed large enough to sweep twelve or fourteen feet in Width.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A smoothing-harrow composed of the frame A A and the series E E' of small straight wires arranged closely together, as. and for the purpose described.`
